Dual WAN - Simultaneous packetloss/latency alarm
-
@michmoor I've inputted a DNS server for gateway monitor IP onWAN#2 DSL connection.. Both my Cable modem and DSL modem are in bypass/bridged mode so no NAT or traffic shaping AFAIK is happening.
I guess beyond this, if the issue persists, could it be the hardware I'm using to run pfSense. -
@steveits yep! I use my service providers DNS service as a monitor.
-
@michmoor The only downside of that is you don't know if they are having an upstream outage in that situation.
-
@rcoleman-netgate Agreed. Per the documentation, it does state to use the ISPs dns server. I tend to shy away from Google DNS or Cloudflare as they are not meant to be a source of ping(reachability).
Do you have a suggestion on what one should monitor?
Funny enough im looking into some outages i had around 2am today. Multiple monitoring endpoints just stopped responding. There was some packet loss on my WAN_DHCP gateway but i dont think that was the problem. More likely something upstream but cant really prove that out. If theres a better method im all ears.
Is there a way to monitor multiple IPs? -
@michmoor said in Dual WAN - Simultaneous packetloss/latency alarm:

I use Google. ¯\_(ツ)_/¯

To me it just doesn't make sense that both WAN connections, different physical modems, ISPs, and lines, experience simultaneous packet loss/drops. Is there any possibility of it being hardware, config, etc. on my pfSense miniPC?

Some additional info:
Primary WAN/default is Cable, Secondary WAN is DSL.
When I unplug the network cable on the Cable-WAN from my router, my secondary WAN/DSL is briefly experiencing packetloss.
2 clients timed out using a continuous ICMP via static rule out secondary-DSL when unplugging cable on primary-WAN.
I don't get why DSL would be interrupted when it has it's own static rules. -
@brewha12 Hmm..The monitor IP isnt pointing to the other right? So cable modem isnt using the DSL Modem as the montior IP?
I assume not as i can see that as the issue.
Assuming it isnt.....im at a lost tbh. -
@brewha12 DSL is using DNS from ISP as GW monitor...thanks for your help.
-
@brewha12 Do you have both WAN connections plugging into a switch OR do they go direclty into their modems
-
@brewha12 both direct to their respective ISp provided modems
